PLOWlNG-MACHINE.

' SPECIFICATION forming part of Letters Patent No. 558,336, dated April 14, 1896.

Application filed April 9, 1895. Serial No. 545,072. (No model.)

To aZZ whom it may concern.-

Be it known that I, ANTON ANDERSON, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Plowing-Machines; and I do hereby declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention is directed to improvements in plowing-machines of that class in which are employed rotary plowshares, and has for its object the production of a simple and cheaply-constructed machine of this character possessing advantages in point of efficiency, inasmuch as I am enabled by my machine to turn. as well as enter the ground by the movement of the shares, owing to their peculiar structure, and also possessing ad vantages in point of durability in that the parts are sectional in character and interchangeable. I have also improved the machine generally with the object of enhancing its value and utility, and will now describe in detail the construction, relative arrangement, and operation of the several parts.

In connection with this description attention is directed to the accompanying drawings, in which Figure 1 is a perspective view of a plowingmachine embodying my invention. Fig. 2 is a plan view of the same. Fig. 3 is a sectional view on line a x of Fig. 2. Fig. 4 is a detail view of one of the rotary plowshares with a portion of the frame for holding the points or blades removed. Fig. 5 is a perspective View of such removable portion of the frame. Fig. 6 is a perspective View of one of the points or blades detached. Fig. 7 is a detail view of one of the bearings which supports two sets of points or blades. Fig. 8 is a perspective view of the scraper.

Referring to the said drawings, in which like letters refer to like parts, A denotes the frame of the gang-plow. B is the frame for the landside. O is the cross-piece, and D is the tongue secured to the latter centrally and by braces 61 d.

The plowshares are of the rotary type, and the series are mounted on an axle e, which is connected to the frame of the series by standards f. Each of the rotary plowshares is composed of separable sections, by which any broken portion may be readily replaced. I have shown each plowshare arranged with six points or blades g g, and each of said points or blades is so shaped as to insure the turning as well as the cutting of the ground after the manner of the point and moldboard of a plow of the ordinary type. To this end the said points or blades are curved continuously from their point of connection to the outer or free end and converge from said point to said outer end, which latter is bluntly pointed. The other .end of said point or blade is segmental in shape, the segment being formed by a line extending straightway from the inner side of the point or blade and by a line arranged at an acute angle to the said inner line, the object of so forming the blades being to fit the inner ends together in a manner to form a circular plowshare with the blades equidistant from each other, and to arrange said blades to one side of the radial lines tan-- gentially, as shown.

The outer end of the blade is designated by g, and g is the segmental inner end, which latter terminates in a stud 9 These blades are secured in the arrangement just described between the heads h h of the journals h, which separate the plowshares and through which the axle e is passed. Each of the heads h is formed on its face near the outer periphery with a series of triangular projections 71. and between said projections or alternating therewith are correspondingly-shaped depressions 71. The face of the adjacent head h is similarly provided with projections and depressions, but the positions of the same difier, the projections on the one entering the depressions on the other, and vice versa. In the present instance shown I employ six blades, and consequently each of the heads is provided alternately with three projections and three depressions.

As before stated, the blades are secured between two heads and the projections and depressions interlocking. When the heads are brought together lateral and circular displacement of the blades is prevented, the projections operating as stops. To preclude radial displacement, the studs 9 on the inner ends of the blades engage the sides of the central opening 7r, which is of sufficient size to receive said studs and also the axle c. This manner of building a rotary plowshare enables new points to be readily substituted for old or broken points, and also facilitates the sharpening of the outer edge of the blades when worn. The peculiar shape and arrangement of the blades facilitate the entrance of the same into the ground, and the cut is followed by the turning over of the ground owing to the shearing action of the blades, which may be also advantageously employed to sever cornstalks or other small obstructions.

To prevent the clogging of the plowshares when plowing muddy or trashy ground, I provide cleaners or clearers i, which are interposed between two plowshares and fill the entire space. My preferred manner of mounting these cleaners is to provide each at its lower end with a half-journal box 2", which partially and loosely embraces one of the journals 72., another halt box i being employed to complete the connection. These cleaners are curved upwardly from the point of conneetion to beyond the path of the outer ends of the blades, and near the top are eyes i, to which is secured one end of a brace rod j, fixed at its other end to the frame. The cleaners are each provided with a large opening i to facilitate the dropping of the dirt cleared from the plowshares.

I employ four standards f to each machine,

and each of said standards is provided at its lower end with a box f, which loosely embraces one of the journals h. The lower half of each box f is provided with an integral eye f the eyes 011 the two inner standards being connected with rods 70 70, which latter in turn are connected to the bifurcated lower end of a lever Z, pivoted to the frame and provided with a spring-actuated pawl Z, engaging a toothed segment Z The purpose of this lever is to regulate by its movement, and consequently by the movement of the inner ends of the frames, the depth of cut. The pawl is released to permit of the movement of the lever by a handle Z. The eyes f onthe outer standards are secured to rods m, which form extensions of the braces (Z (Z, and f are eyes in the upper ends of said outer standards to permit of connection therewith of braces 'n, which are bolted at their other ends to the cross-bar.

Having now fully and clearly described my invention, what I claim isl. A rotary plowshare comprising two clamped-together heads, and blades each having a lateral stud or projection at its inner end and substantially in alinement with a longitudinal edge thereof, with its said inner end standing radially to the center of said heads and the blades themselves tangentially to said center, as set forth.

2. A rotary plowshare comprising two clamped-together heads having interlocking studs and recesses and a central opening, and blades arranged between said interlocking studs or projections and recesses and each blade having a lateral stud or projection at its inner end, substantially in alinement with a longitudinal edge thereof and engaging said central opening with its inner end standing radially to the center of said heads and the blades, themselves, tangentially to said center, as set forth.

3. In combination with a rotary plowshare and with a journal on the axle, of a cleaner adjacent to the blades of the plowshare, and having loose connection with said journal and a brace securing the upper end of the cleaner to the frame.

4. In a plowing-machine, the combination of the tongue, the cross-bar seoured'thereto by braces having rearward extensions, the frames for the gangs, standards securing the gangs to the frames, the outer standards being connected with said extensions and having brace connection with the crossbar, the inner standards having connection with a regulating-lever, the rotary plowshares each composed of removable blades tangentially arranged and cleaners adjacent to the blades and having brace connection with the frame and loose connection with the journals between which said shares are secured.

In testimony whereof I alfix my signature in presence of two witnesses.

ANTON ANDERSON.
